data

facts and statistics collected together for reference or analysis

dependent or outcome variable

empirical

based on observations and measurements you can test not just ideas

experiment

testing dependent and independent variables, uses the scientific method, establishes a cause and effect

hypothesis

independent or test variable

a factor that can be varied or manipulated in an experiment

materials

things needs for an activity

model

a diagram or object that shows how something works or looks

observation

using all of your senses and scientific instruments to describe a thing or event

repetition

all scientific experiments must be able to be repeated following the procedures

results

conductivity

hardness

how resistant an object is to being scratched or dented

volume

the amount of space an object takes up, measured in L or cm³

weight

the force of gravity on an objects mass, measured in N or lbs
